Previously known open-source Android spyware makes its debut on Google Play

ESET researchers have discovered the first known instances of spyware based on the open-source espionage tool called AhMyth. This particular spyware was posing as an internet radio app playing very specific Balochi music; however, the spying capabilities may be easily attached to any other app.

AhMyth, from which the internet radio app borrowed its malicious functionality, was made publicly available in late 2017. Since then, various malicious apps based on AhMyth have appeared. However, the above-mentioned app, named Radio Balouch, is the very first of them to make it onto the official Android app store, Google Play.

REsearcher from ESET says that the malicious functionality in AhMyth is not hidden, protected, or obfuscated. For this reason, it is trivial to identify the Radio Balouch app – and other derivatives – as malicious and classify them as belonging to the AhMyth family.

After ESET reported the discovery to Google, its security team removed the malicious Radio Balouch app from the store. The attackers, however, were quick to make the app reappear on Google Play. They also detected and reported the second instance of this malware, which was then swiftly removed. However, the fact that Google let the same developer post this evident malware to the store repeatedly is disturbing according to ESET.

Radio Balouch, detected by ESET as Android/Spy.Agent.AOX, has been promoted on a dedicated website, Instagram, and YouTube. After having been removed from Google Play, it is now only available on alternative app stores.

This app is a fully functional internet radio application for music specific to the Balochi region. In the background, however, it spies on its users: it can steal contacts and harvest files stored on the affected device. According to ESET the open-source AhMyth espionage tool has a number of variants whose functionalities vary. The Radio Balouch app – and any other AhMyth-based malware, may receive further functions in the future.

According to ESET researchers, unless Google improves its safeguarding capabilities, a new clone of Radio Balouch or any other derivative of AhMyth may soon appear on Google Play.
